Need help with first byte time

[mnovick]

I do have access to install software, and have installed New Relic and am starting to see some results trickle in. There is a LOT to this tool, and it's tough to tell what exactly I'm looking at, and what I should be looking for. Tips?

Another question about New Relic - I do some back-end php processing that takes a long time - basically an import routine that updates periodically to give results. Because of this, the import routine seems to be throwing off all my stats because this one page (import.php) takes a long time to load. Is there a way to exclude it from the results? I really don't care how long that page takes to load (although am concerned with how other pages load WHILE I am running the import routine).
